The game aesthetically is nice, but the gameplay is not really enjoyable since you are completely out of control of what happens. Perhaps instead of give both the player and the opponent a set amount of cards to last up to three rounds and each player chooses what card to put down and the higher number wins. (Sort of like the game war). And possibly remove those cards from future rounds. If you do add onto it in the future you have to follow that, but giving the player some control over the outcome I think is important.
